NOD32 settings affecting ADSL2 speed

We recently upgraded to ADSL2 and were expecting a significant improvement in speed. In reality we've seen no improvement in speed etc etc which led me to contact Telstra BigPond. One of the things they asked me to do was to disable my anti-virus program and run the speed test again.

Before I disabled NOD32 speeds were -

Download - 169kbps
Upload - 37 kbps
QOS - 39%

When I disabled NOD32 speeds were -

Download - 2.5Mbps
Upload - 316kbps
QOS - 0%

So it seems that my NOD32 settings are affecting the speed.

I went in and had a look and noticed that there are settings that look like they could be changed but I don't know what to do.

I wasn't aware that there was a more recent version available until I did some searching in this forum (why doesn't ESET notify us of these updates?). But when I read the following thread I wasn't confident that it will resolve my problem.

Hopefully this takes you to the follow Posting which includes the quote below...........

Internet slow after v3 install, any help appreciated

Uninstalled the old version and downloaded & installed v 3 0 621.

Good news, it is somewhat faster. For example I can now click my back button and generally get to the prev page in less than 5 seconds. This is a huge improvement...it was taking 10+ seconds. So I appreciate the tip to get the current version.

Bad news, it's still unreasonably slow at other times. I wish I knew how to quantify - It seems like the first time I'm at a site, it's always slow. If I return to the site later, it might load faster...or it might not. Prior to NOD32 I had pretty consistent speeds regardless of the site with Firefox and IE. Any ideas?

I tested my up/down speeds and they are the same before & after installing 621. So I don't think that is a factor.
